A. S. PERRIGO, OF SANDWICH, ILLINOIS.

IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 95,505, dated October5, 1869.

To all whom it may concern.-

Be it known that I, A. S. PERRIGO, of Sandwich, in the county of De Kalband State of Illinois, have invented an Improved Cultivator; and I dohereby declare that the following is a full and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the accompanying drawings and lettersmarked thereon, making a part of this specification, in which Figure 1is a perspective representation of my improved cultivator. 'Figs. 2, 3,4, and 5 are parts appertaining thereto, detached from the cultivator togive a clearer view of their construction.

The nature of the present invention consists in the novel manner inwhich the forward ends of the beams are held to the axle, adjusted to orfrom each other, and adjusted to gage the depth which the shovels are torun in the ground; second, in combination with the devices foraccomplishing the above, draft-rods and braces, which strengthen theframe-work and give a proper line of draft; third, the novel means usedto hold the shovels to the standards,- fourth, the novel construction ofthe adjustable rod which gages the distance which the shovels are tohave from each other, as the whole is hereinafter fully specified.

A A represent the wheels, and B the elevated axle which supports theshovel-beams of the cultivator, and which have the ordinary constructionused for a like purpose. To the under side of the axle B, and near itstwo ends, are attached depending standards K K, to which, by means ofbolts L L, are pivoted clips M M, Fig. 1. These clips have a series ofvertical holes, N, made through them, in order that the beams A A may beadjusted to or from each other. The beams are held to the clips M bymeans of twopart clevises Q Q, which are pivoted to the beams at a a,and so formed at their forward ends, Q Q, as to overlap both sides ofthe clips M, and fasten to each of them by a single pivot-bolt, D, andwhich have their rear ends, T, so enlarged and slotted out as to beadjusted to a greater or less height on bolts S, put through the beams,and used to hold said clevises rigidly in place when adjusted. Thenature of this arrangement is such that the rear shovels can be made torun the same depth. in the ground as the forward ones, no matter whatposition the latter may occupy. The forward ends of the clips M areslotted out parallel with the depending standards K K deeply enough toallow draft-rods E and brace-rods B to fasten onto the pivot-bolt L,Fig. 1. These draftrods are made of a single iron rod each, passing fromthe clips M through depending hooks D, and fastened to the iron arms Jof the axle B. The opposite ends of the braces B from the clips M fastento the braces O O of the tongue G, by means of which the cultivator isvery much strengthened, and the draft is fully equalized quite nearly ona line with the beams A. The device for holding the shovelstandards V Vany required distance apart consists of rods (1 0, Figs. 1 and 5,jointed to the top of said standards and locked together by means of acam, e, pivoted to a clamp, f, attached to the end of rod d. Thisarrangement is such that the rod 0 may slide freely in the clamp f, orbe held by said cam. to the standards V by the following devices as tobe set at any required angle. Clamps Y Y are so formed as to clasp ontothe standards and onto metal bars 0, fastened to the backs of theshovels, as shown at Fig. 4, said clamps being held in place by boltsand nuts Z X, and the inner ends of the clamps being notched out to fitthe angular shape of the said bars 0.

Having thus described my invention, What I claim, and desire to secureby Letters Patent of the United States, is

1. The two-part clevises Q, pivoted to the beams A and to the clips M,and provided with slotted ends T, for adjusting the depth which theshovels are to run in the ground, as set forth.

2. The combination of the clevises Q, clips .M, and standards K, asdescribed.

3. The combination of the clevises Q, standards K, clips M, and rods BE, as and for the purpose set forth.

4. The combination of the rods d a, standards V, shovels U, and cam e,for holding the shovels the required distance apart, as specified.

5. The two-part clamp YY, in combination with the standard V, bolt andnut Z X, angular bar 0, and shovel U, for holding and adjusting saidshovel, as described.
